A barcode system is a method used to identify and track products using a series of parallel lines and spaces, known as a barcode. Each barcode represents specific information about the item, such as its price, manufacturer, and product type. Scanners read these barcodes, converting them into digital data that can be processed by computers. These systems are widely used in various industries, including retail, logistics, and healthcare. By automating the identification process, barcode systems improve efficiency, reduce errors, and streamline inventory management. This technology has become essential for businesses to manage their products effectively.
